Knockdown of CPSF4 Inhibits Bladder Cancer Cell Growth by Upregulating NRF1.	Increasing studies have shown that nuclear respiratory factor 1 (NRF1) deficiency frequently occurs in many human diseases, and its activation can protect neurons and other cells from degenerative diseases and malignant tumors. However, how NRF1 is regulated in bladder cancer remains unknown. Our research aims to reveal the role of leavage and polyadenylation-specific factor 4 (CPSF4) on the growth inhibition effect of bladder cancer and clarify its relationship with NRF1. Here, cell proliferation assay, transwell migration assay and multicellular tumor spheroids (MCTS) formation assay in the bladder cancer cell lines were carried out to measure tumor cell growth. Western bolt assay was carried out to identify the relationship between NRF1 and CPSF4. Also, subcutaneous xenograft tumors in nude mice were established to further validate the inhibition effect of CPSF4 on bladder tumor and the regulation on NRF1. The results in vitro showed that knockdown of CPSF4 strongly reduced the proliferation and migration, and inhibited MCTS formation in 5637 and HT1376 cell lines, while an additional knockdown of increased NRF1 induced by CPSF4 knockdown partially abolished these effects. The results in vivo showed that knockdown of CPSF4 strongly reduced the volume and weight of subcutaneous tumor, and decreased the expression of Ki-67 in tumor tissue, while NRF1 knockdown partially reversed these effects induced by CPSF4 knockdown. Western bolt assay demonstrated that CPSF4 could negatively regulate NRF1. Our results indicated that knock-down of CPSF4 inhibited bladder cancer cell growth by upregulating NRF1, which might provide evidence of CPSF4 as a therapeutic target for bladder cancer.	bladder
A novel laser resection approach: efficacy of rotatable bi-channel en bloc resection of bladder tumor in a pilot in-vivo study.	En bloc resection of bladder tumor (ERBT) involves removing bladder tumors and their base. Laser resection has been used to reduce complications including bleeding and obturator nerve reflex (ONR). We developed a novel approach (rotatable bi-channel en bloc resection of bladder tumor (RBC-ERBT)) and assessed its efficacy in a pilot in-vivo study to enhance laser ERBT's applicability in challenging bladder regions. In the laser RBC-ERBT procedure, lesions were excised by inserting a holmium laser through the rotating external working channel, while forceps were inserted through the internal working channel provided traction on the tissue. Fifteen laser RBC-ERBT procedures were performed in five different bladder areas of three live pigs. The technical success rate (TSR), procedure time, lesion size, occurrence of complications (bleeding, perforation, ONR), and detrusor muscle (DM) presence rate and DM thickness were evaluated. All 15 procedures were performed with a 100% TSR. The resections were successful in all bladder regions (posterior, left, right and anterior walls and dome). Median procedure time was 20 min. The resected specimen size was 10 mm × 7 mm to 17 mm × 13 mm. Mild bleeding occurred in two procedures (13.3%) but was effectively managed. No incidents of ONR or perforation were observed. Histological examination confirmed presence of DM in all specimens with a median DM thickness of 1.26 mm. Our pilot in-vivo study suggested the feasibility and effectiveness of laser RBC-ERBT for bladder tumors in various locations. This technique offers effective traction, improved visualization, and enhanced laser accessibility. Further studies are required to validate its effectiveness in humans.	bladder
The prognostic significance and immune characteristics of bone morphogenetic proteins (BMPs) family: A pan-cancer multi-omics analysis.	BACKGROUND: Bone morphogenetic proteins (BMPs) are a group of cancer-related proteins vital for development and progression of certain cancer types. Nevertheless, function of BMP family in pan-cancer was not detailedly researched. OBJECTIVE: Investigating expression pattern and prognostic value of the BMPs family (BMP1-8A and BMP8B) expression across multiple cancer types. METHODS: Our research integrated multi-omics data for exploring potential associations between BMPs expression and prognosis, clinicopathological characteristics, copy number or somatic mutations, immune characteristics, tumor microenvironment (TME), tumor mutation burden (TMB), microsatellite instability (MSI), immune checkpoint genes and drug sensitivity in The Cancer Genome Atlas (TCGA) tumors. Furthermore, association of BMPs expression and immunotherapy effectiveness was investigated in some confirmatory cohorts (GSE111636, GSE78220, GSE67501, GSE176307, IMvigor210 and mRNA sequencing data from currently undergoing TRUCE01 clinical research included), and biological function and potential signaling pathways of BMPs in bladder cancer (BCa) was explored via Gene Set Enrichment Analysis (GSEA). Eventually, immune infiltration analysis was done via BMPs expression, copy number or somatic mutations in BCa, as well as validation of the expression levels by reverse transcription-quantitative PCR and western blot, and in vitro functional experiments of BMP8A. RESULTS: Discoveries displayed BMPs expression was related to prognosis, clinicopathological characteristics, mutations, TME, TMB, MSI and immune checkpoint genes of TCGA tumors. Anticancer drug sensitivity analysis displayed BMPs were associated with various drug sensitivities. What's more, it was discovered that expression level of certain BMP family members related to objective response to immunotherapy. By GSEA, we discovered multiple immune-associated functions and pathways were enriched. Immune infiltration analysis on BCa also displayed significant associations among BMPs copy number variations, mutation status and infiltration level of diverse immune cells. Furthermore, differential expression validation and in vitro phenotypic experiment indicated that BMP8A significantly promoted BCa cell proliferation, migration and invasion. CONCLUSIONS: Current results confirmed significance of both BMPs expression and genomic alteration in the prognosis and treatment of diverse cancer types, and suggested that BMPs may be vital for BCa and can possibly be utilized as biomarkers for immunotherapy.	bladder
Prognostic analysis of anoikis-related genes in bladder cancer: An observational study.	Anoikis is proved to play a crucial role in the development of cancers. However, the impact of anoikis on the prognosis of bladder cancer (BLCA) is currently unknown. Thus, this study aimed to find potential effect of anoikis in BLCA. The Cancer Genome Atlas (TCGA)-BLCA and GSE13507 cohorts were downloaded from TCGA and the Gene Expression Omnibus (GEO) databases, respectively. Differentially expressed genes (DEGs) were screened between BLCA and normal groups, which intersected with anoikis-related genes to yield anoikis-related DEGs (AR DEGs). Univariate COX, rbsurv, and multivariate COX analyses were adopted in order to build a prognostic risk model. The differences of risk score in the different clinical subgroups and the relevance between survival rate and clinical characteristics were explored as well. Finally, chemotherapy drug sensitivity in different risk groups was analyzed. In total, 78 AR DEGs were acquired and a prognostic signature was build based on the 6 characteristic genes (CALR, FASN, CSPG4, HGF, INHBB, SATB1), where the patients of low-risk group had longer survival time. The survival rate of BLCA patients was significantly differential in different groups of age, stage, smoking history, pathologic-T, and pathologic-N. The IC50 of 56 drugs showed significant differences between 2 risk groups, such as imatinib, docetaxel, and dasatinib. At last, the results of real time quantitative-polymerase chain reaction (RT-qPCR) demonstrated that the expression trend of CALR, HGF, and INHBB was consistent with the result obtained previously based on public databases. Taken together, this study identified 6 anoikis-related characteristic genes (CALR, FASN, CSPG4, HGF, INHBB, SATB1) for the prognosis of BLCA patients, providing a scientific reference for further research on BLCA.	bladder
An assessment of the direct and indirect costs of bladder cancer preceding and following a cystectomy: a real-world evidence study.	INTRODUCTION: To estimate the direct and indirect costs of bladder cancer prior to and following cystectomy in a U.S. sample of patients. METHODS: This retrospective, observational analysis of de-identified patients with bladder cancer utilized the MarketScan Commercial Claims & Encounters and Health & Productivity Management databases. Adult patients with bladder cancer plus ≥ 1 claim for partial or radical cystectomy between 1 October 2015 and 31 December 2020 (date of the cystectomy = index date) and who were continuously enrolled for 6 months pre- (baseline) and post-index (follow-up) were included in the sample. All-cause total healthcare costs and indirect costs associated with short-term and long-term disability (STD and LTD) employer claims were assessed during each of the 6-month baseline and follow-up periods. RESULTS: The study included N = 142 patients; mean age 56 ± 6 years, 76% (male), and 42% had a baseline Deyo-Charlson Comorbidity Index ≥ 2. Baseline mean total all-cause direct healthcare costs were $51,473 ± $48,560 (median: $36,202), and $99,524 ± 86,839 (median: $75,444) during follow-up. At baseline, 32% of patients had ≥ 1 STD claim, equating to a mean 134 ± 303 h lost and $2,353 ± $6,445 in total payments per patient. Follow up STD claims increased 23.4% equating to a mean 218 ± 324 h lost and $3,679 ± $7,795 per patient. Patient LTD claims increased from baseline to follow-up (1-3%), with post-cystectomy LTD claims resulting in 574 ± 490 h lost, and $1,636 ± $1,429 in total payments. Over 85% of the population had a cystectomy related complication, the most common were genitourinary-related (47.9%) and infection/sepsis (33.1%). CONCLUSIONS: Cystectomy was associated with complications and decreased work productivity post-surgery. Findings may aid to inform decisions regarding cystectomy vs. bladder preservation approaches, and underscores an ongoing need to further develop bladder preservation therapies within the bladder cancer treatment landscape.	bladder
Analysis of early perioperative outcomes of robot-assisted radical cystectomy and colonic diversion.	Studies of right colon pouch urinary diversion have widely varying estimates of the risk of perioperative complications, reoperation, and readmission. We sought to describe the association between specific risk factors and complication, readmission, and reoperation rates following right colon pouch urinary diversion. Patients undergoing robot-assisted right colon pouch urinary diversion from July 2013 to December 2022 were analyzed. Outcome measures include high-grade (Clavien-Dindo grade ≥ 3) complications within 90 days, readmission within 90 days, and reoperation at any time during follow-up. Specific risk factors such as age, gender, body mass index (BMI), diabetes, Charlson comorbidity index (CCI), and prior radiation were analyzed to establish an association with these outcomes. During the study period, 77 patients underwent the procedure and were eligible to study. The average follow-up was 88.7 (SD 14) months. 90-day high-grade complications were 24.67%, and 90-day readmission was 33.76%. The cumulative rate of any reoperation was 40.2%, and major reoperation was 24.67%. Female gender (OR 3.3, p = 0.015), 1 kg/m(2) increase in BMI (OR 3.77, p = 0.014), diabetes (OR 3.49, p = 0.021), higher CCI (OR 1.59, p = 0.034), prior radiation (OR 1.97, p = 0.026), lower eGFR (OR 0.99, p = 0.032) and BMI ≥ 25 kg/m(2 ) (OR 3.9, p value 0.02) was associated with Clavien III-IV complications. Female gender (OR 3.3, p = 0.015), diabetes (OR 3.97, p = 0.029), higher Charlson Comorbidity Index (OR 1.73, p = 0.031), prior radiation (OR 1.45, p = 0.029), lower eGFR (OR 0.87, p = 0.037) and BMI ≥ 25 kg/m(2) (OR 3.86, p = 0.031) were predictive of reoperation. Overall, the rate of postoperative complications, readmissions, and reoperation was high but consistent with other studies. This study helps further characterize surgical outcomes after right colon pouch urinary diversion and highlights patients who may benefit from enhanced preoperative management for minimising complications.	bladder
Prevalence of diabetes and hospitalization due to poor glycemic control in people with bladder cancer or renal cell carcinoma in Sweden.	BACKGROUND: Bladder cancer (BC) and Renal cell carcinoma (RCC) are the most common urogenital cancers among both sexes, with a yearly global incidence of around 500 000 each. Both BC and RCC have been linked to diabetes. Poor glycemic control (malglycemia) is a serious consequence of diabetes and a possible consequence of systemic treatments used in BC and RCC. The objective of this study was to investigate the prevalence of diabetes and use of hospital-based care for malglycemia in people with BC or RCC. METHODS: This Swedish retrospective population-based register study used national health-data registers for longitudinal data on cancer incidence covering 15 years, use of hospital-based health care, and filled prescriptions of outpatient medications. Study endpoints included co-prevalence of diabetes in individuals with BC/RCC, healthcare resource utilization due to malglycemia, use of systemic corticosteroids, and changes in diabetes management for people with concomitant type 2 diabetes. RESULTS: We identified 36,620 and 15,581 individuals diagnosed with BC and RCC, respectively, between 2006 and 2019. The proportion of individuals registered with diabetes was 24% in BC and 23% in RCC. An association between BC/RCC and poor glycemic control was found, although the number of malglycemic events in hospital-based care were few (65/59 per 1000 individuals with diabetes and BC/RCC respectively with at least one event). An earlier switch to insulin-based diabetes management was observed in BC/RCC compared to matched individuals with type 2 diabetes but no cancer. The results also indicated an association between steroid treatment and poor glycemic control, and that systemic corticosteroids were more common among people with BC/RCC compared to diabetes controls. CONCLUSION: The high prevalence of diabetes and increased use of systemic corticosteroid treatment observed in this large national study highlights the need for specific clinical management, risk-assessment, and monitoring of individuals with BC/RCC and diabetes.	bladder
Phase 3 THOR Japanese subgroup analysis: erdafitinib in advanced or metastatic urothelial cancer and fibroblast growth factor receptor alterations.	BACKGROUND: In the THOR trial (NCT03390504) Cohort 1, erdafitinib demonstrated significantly prolonged overall survival (OS) (median 12.1 versus 7.8 months) and reduced risk of death by 36% (hazard ratio 0.64, P = 0.005) compared with chemotherapy in metastatic urothelial carcinoma (mUC) patients with FGFR alterations who progressed after ≥ 1 prior treatments, including anti-PD-(L)1. There have been no reports of the Japanese subgroup results yet. METHODS: THOR Cohort 1 randomized patients to erdafitinib once daily or docetaxel/vinflunine once every 3 weeks. Primary endpoint was OS. Secondary endpoints included progression-free survival (PFS) and objective response rate (ORR). No specific statistical power was set for this Japanese subgroup analysis. RESULTS: Of 266 patients randomized, 27 (14 erdafitinib; 13 chemotherapy) were Japanese. Baseline characteristics were generally similar between treatments and to the overall population, except for more males, lower body weight, and more upper tract primary tumors among Japanese patients. Compared with chemotherapy, erdafitinib showed improved OS (median 25.4 versus 12.4 months), PFS (median 8.4 versus 2.9 months) and ORR (57.1% versus 15.4%). Any grade treatment-related adverse events (AEs) occurred in all patients from both arms but Grade 3/4 AEs and AEs leading to discontinuation were lower in the erdafitinib arm. No new safety signals were observed in the Japanese subgroup. CONCLUSION: In the Japanese subgroup, erdafitinib showed improved survival and response compared to chemotherapy, with no new safety concerns. These results support erdafitinib as a treatment option for Japanese mUC patients with FGFR alterations, and early FGFR testing after diagnosis of mUC should be considered.	bladder
Advanced optical imaging techniques for bladder cancer detection and diagnosis: a systematic review.	OBJECTIVES: To systematically assess the current available literature concerning advanced optical imaging methods for the detection and diagnosis of bladder cancer (BCa), focusing particularly on the sensitivity and specificity of these techniques. METHODS: First a scoping search was performed to identify all available optical techniques for BCa detection and diagnosis. The optical imaging techniques used for detecting BCa are: the Storz professional image enhancement system (IMAGE1 S), narrow-band imaging (NBI), photoacoustic imaging (PAI), autofluorescence imaging (AFI), photodynamic diagnosis (PDD), and scanning fibre endoscopy (SFE). The staging and grading techniques for BCa are: optical coherence tomography (OCT), confocal laser endomicroscopy (CLE), Raman spectroscopy, endocytoscopy, and non-linear optical microscopy (NLO). Then a systematic literature search was conducted using MEDLINE, EMBASE and Web of Science from inception to 21 November 2023. Articles were screened and selected by two independent reviewers. Inclusion criteria were: reporting on both the sensitivity and specificity of a particular technique and comparison to histopathology, and in the case of a detection technique comparison to white light cystoscopy (WLC). RESULTS: Out of 6707 articles, 189 underwent full-text review, resulting in 52 inclusions. No articles met criteria for IMAGE1 S, PAI, SFE, Raman spectroscopy, and endocytoscopy. All detection techniques showed higher sensitivity than WLC, with NBI leading (87.8-100%). Overall, detection technique specificity was comparable to WLC, with PDD being most specific (23.3-100%). CLE and OCT varied in sensitivity and specificity, with OCT showing higher specificity for BCa diagnosis, notably for carcinoma in situ (97-99%) compared to CLE (62.5-81.3%). NLO demonstrated high sensitivity and specificity (90-97% and 77-100%, respectively) based on limited data from two small ex vivo studies. CONCLUSIONS: Optical techniques with the most potential are PDD for detecting and OCT for staging and grading BCa. Further research is crucial to validate their integration into routine practice and explore the value of other imaging techniques.	bladder
[Urinary diversion in old patients (80+ years)].	With increasing life expectancy there is also an increased need for the management of older (≥ 80 years) patients with the diagnosis of muscle-invasive bladder cancer. Radical cystectomy with urinary diversion is the state of the art treatment (with neoadjuvant chemotherapy, as long as the patient is fit enough). Choosing the best urinary diversion with respect to morbidity compared to functionality and quality of life remains a challenge in these patients. Physical age alone is not decisive for making a decision. A thorough preoperative assessment of medical features, physical and cognitive impairments is more important. Older patients are generally provided with an ileal conduit as an incontinent urinary diversion, as the intervention involves reduced operating times and complexity compared to continent urinary diversions; however, in the case of good health status with an adequate life expectancy and sufficient compliance, continent diversions may be considered even in aged candidates. In the case of multimorbid patients with a high perioperative risk, ureterostomy with permanent ureteric stents is an important alternative. Most importantly, a thorough preoperative counselling enables patients to reach an informed decision.	bladder
Nano-Bacillus Calmette-Guérin immunotherapies for improved bladder cancer treatment.	Cancer immunotherapy has rapidly become the fourth mainstream treatment alternative after surgery, radiotherapy, and chemotherapy, with some promising results. It aims to kill tumor cells by mobilizing or stimulating cytotoxic immune cells. However, the clinical applications of tumor immunotherapies are limited owing to a lack of adequate delivery pathways and high toxicity. Recently, nanomaterials and genetic engineering have shown great potential in overcoming these limitations by protecting the delivery of antigens, activating targeted T cells, modulating the immunosuppressive tumor microenvironment, and improving the treatment efficacy. Bacillus Calmette-Guérin (BCG) is a live attenuated Mycobacterium bovis vaccine used to prevent tuberculosis, which was first reported to have antitumor activity in 1927. BCG therapy can activate the immune system by inducing various cytokines and chemokines, and its specific immune and inflammatory responses exert antitumor effects. BCG was first used during the 1970s as an intravesical treatment agent for bladder cancer, which effectively improved immune antitumor activity and prevented tumor recurrence. More recently, nano-BCG and genetically engineered BCG have been proposed as treatment alternatives for bladder cancer due to their ability to induce stronger and more stable immune responses. In this study, we outline the development of nano-BCG and genetically engineered BCG for bladder cancer immunotherapy and review their potential and associated challenges.	bladder
Clinical characteristics and factors associated with survival rate of patients with non-muscle invasive bladder cancer attending at a Tertiary Hospital in Somalia.	BACKGROUND: A few studies regarding the epidemiology and risk factors of Non-muscle Invasive Bladder Cancer (NMIBC) are reported from Sub-Saharan African countries (SSA), including Somalia, and the African literature is scant on the management of NMIBC. The present study aims to evaluate the clinical-histopathological characteristics and factors associated with the survival rate of patients with NMIBC. METHOD: This six-year cohort study included 196 patients with NMIBC. It reviewed the clinical and histopathological characteristics and factors predicting cancer-specific survival for these patients. RESULTS: The mean patient age was 59.01 ± 11.50 years, with a male-to-female ratio of 2.8:1. Urothelial carcinoma (UC) constituted the most common pathological type, accounting for 90.8%; Ta LG and T1HG were the most common histopathological tumour stage and grade (n = 90, 45.9%, vs. n = 56, 28.6%), respectively. The mean tumour size was 4.72 ± 2.81 cm. The cancer-specific mortality(CSM) was 13.3%. Age [2.252(2.310-2.943], p < 0.001], Gender [1.031(0.981-1.1.242),p < 0.001], tumour stage and grade [4.902(3.607-5.614),p < 0.001], tumour location [1.135(0.806-1.172),p < 0.001], number [0.510(0.410-0.920),p = 0.03], tumour size [1.523(0.936-1.541),p < 0.001], use of intravesical chemotherapy or BCG [2.810(1.972-4.381),p < 0.001], preoperative hydronephrosis grade [1.517(1.172-2.154),p < 0.001], and follow-up compliance [3.376(2.633-5.018),p < 0.001] were all associated with CSM. The 5-year overall survival was 57.1%, and cardiovascular diseases were the leading cause of mortality (n = 34), followed by diabetes (n = 28). CONCLUSION: Our study findings revealed that UC constituted the most common pathological subtype, though less than forty per cent of our patients receive intravesical adjuvant therapies, which are crucial to minimizing disease morbidity and mortality. Initiatives improving uro-oncological care, including subspecialty training in oncology and essential cancer therapies, better access to urology services, and cancer screening programs, are much needed for optimal management plans and care in the country.	bladder
